About this study
Official title: Efficacy and Safety of Sublingual Immunotherapy With House Dust Mite Extract in Asthmatic Children: A Double-Blind, Randomized, and Placebo-Controlled Study
Asthma, the airway inflammatory disorder, is an important chronic disease in children. About 10~15% children are bothered with this. Allergens, such as house-dust mites (HDM), animal dander (i.e. cats and dogs), and seasonal pollens, are often implicated as causative and triggering factors of respiratory attacks in children with asthma. Among them, mites are the most common indoor allergen associated with asthma worldwide.
It appears that SLIT is somewhat effective and safe. However, on the current evidence, further studies are needed to define the indications, the duration of treatment and therapeutic optimal dose of standardized allergen extracts in relation to efficacy and side effects before it is recommended for routine clinical use. The objective of the present study was to investigate the effects and safety of StaloralTM, the standardized extracts of D. pt. and D. f., in asthmatic children allergic to HDM.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Staloral TM in people with Asthma, run by National Taiwan University Hospital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 3 Nov 2005. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Li-Chieh Wang, MD (886-2-23123456 ext. 5127, lcwang5@ha.mc.ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change of asthmatic scores from baseline. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2005.
